Abstract

The camera or periscope system may include a taking lens, a beam steering device, a relay device, and an image rotation device. The camera or periscope system can be used to image in situations where the camera is not easily redirected to view a desired object of interest. The camera or periscope system is designed to be fixed to a mounting platform where the taking lens can be configured to point to the desired object of interest.

Claims

exact text as granted — not AI-modified

       13. The periscope system of  claim 1 , wherein the relay lens changes the intermediate image size to match a desired image format. 
     
     
       14. The periscope system of  claim 1 , wherein the relay lens comprises a plurality of different relay lenses having different magnifications. 
     
     
       15. The periscope system of  claim 1 , wherein the image rotation device comprises a Pechan prism. 
     
     
       16. The periscope system of  claim 1 , wherein the image rotation device comprises a Compact prism. 
     
     
       17. The periscope system of  claim 1 , wherein the beam steering device comprises 3 right angle prisms and a field lens, the relay lens is a straight multi-element lens assembly, and the image rotation device is a Pechan prism. 
     
     
       18. The periscope system of  claim 1 , wherein the relay lens comprises a zoom lens. 
     
     
       19. A fully articulated periscope system comprising:
 a housing; 
 a taking lens configured to receive light that produces an image; 
 a first right angle prism positioned adjacent to the taking lens, configured to receive the light from the taking lens, and configured to redirect the light at a first substantially right angle; 
 a field lens positioned adjacent to the first right angle prism and configured to receive the light from the first right angle prism; 
 a second right angle prism positioned adjacent to the field lens, configured to receive the light from the field lens, and configured to redirect the light at a second substantially right angle; 
 a third right angle prism positioned adjacent to the second right angle prism, configured to receive the light from the second right angle prism, and configured to redirect the light at a third substantially right angle; 
 a relay lens positioned within the housing and configured to receive the light from the third right angle prism; and 
 a Pechan prism configured to receive the light from the relay lens and rotate the image.
